Question

9. The angles A, B, C and D of a quadrilateral are in the ratio 2:3:2:3. Show that
this quadrilateral is a parallelogram.​

Answer 1

Answer:

let,the sum of All angles of quadrilateral are 180°

now, total ratio =2+3+2+3 =10

a to q,

angle of a =2/10×180 =36°

angle of b =3/10×180 =54°

angle of c =2/10×180 =36°

and angle of d =3/10×180 =54°

All angles sum = 36°+54°+36°+54° =180°
